Understanding
kidney function.
Understand the role of your kidneys and what a kidney function blood test can tell you.
What you need to know.
Your kidneys help remove waste, regulate fluid balance and maintain the balance of minerals in the body. Kidney problems can develop gradually or suddenly. Early chronic kidney disease may cause few symptoms, making appropriate testing important for people at risk.
Signs & symptoms
- Early kidney disease may have no noticeable symptoms
- Swollen ankles or feet
- Persistent tiredness
- Changes in urination
Factors to discuss
- Diabetes
- High blood pressure
- A family history of kidney disease
- Previous kidney problems or acute kidney injury
What testing can tell you.
Kidney function is included in Essential, Advanced and Performance & Longevity. Blood tests can help assess kidney function; your doctor may also recommend urine tests or repeat blood tests depending on the results and your history.
A blood test alone does not check for every kidney condition. A normal result does not replace assessment of symptoms or ongoing monitoring advised by your doctor.
Your next step
If you have symptoms or a specific health concern, speak to your GP. If you’re choosing a routine health screen, review the package’s included tests or ask our team for help.
